McCracken races to stop a terrorist attack on the State of the Union speech and confronts an ancient weapon of unimaginable power.

Blaine McCracken has just pulled off the impossible in Iran, ridding the world of a terrible threat—only to return home to face another. The reverend Jeremiah Rule spews hateful rhetoric and inflames half the world, setting off a series of devastating terrorist attacks. Rule, though, isn’t acting alone. A shadowy cabal is pulling his strings, unaware that they are creating a monster who’s about to spin free of their control.

Finding himself a wanted man, McCracken must draw on skills and allies both old and new to get to the heart of a plan aimed at unleashing no less than the tenth circle of hell. A desperate chase across country and continent takes him into the past, where the answers he needs hide in some of history’s greatest unsolved mysteries. As the clock ticks down to an unthinkable maelstrom, McCracken and his trusty sidekick Johnny Wareagle fight to save the United States from a war that the country didn’t even know it was fighting – but that it may well lose.
